Is Oumumua an alien ship?

Nice to see that kind of question. When we are looking at this kind of thing, we must keep our minds open. We cannot or at least we shouldn't say that Oumuamua is not alien spacecraft. Or otherways saying there is no evidence that Oumuamua is alien spacecraft either. nobody has ever seen the stone surface of that asteroid except the radar images. Let's think about the hypothesis, that Oumumua could be the alien probe. Not manned craft. So the Oumuamua could be the only computer or interstellar Voyager spacecraft, that collects data and sends it to its creators.

There is no human or known probe, which has landed and taken samples of Oumuamua, the asteroid from another star. Could Oumumua from Van Maanen 2 star, what has been similar with the sun, before it was detonated and turned to a white dwarf, what is the fate of our sun.

Could it the spacecraft or probe, what mission is to search the habitable solar system? And now let's go about facts. The fact is that Oumumua is the object, that is covered by ice. So there is no spectroscope analysis about that object itself. And there was no radio transmitting coming from that object. So is it sure that Oumumua is not the alien probe?

In many scenarios, the interstellar probes are covered by ice, which protects them against micro and larger asteroids. And of course, the Oumumua could be the "sleeping" probe, whose mission was to travel to our solar system, make the observations, and then send that data to the home star to civilization, what built it. The probe would travel in space by using its passive systems, and when it sees something interesting, it might record things, and then transmit data to its senders. Or probe might be "dead" the old garbage, which is run out of its fuel.

So there are many times written that Oumuamua was only an asteroid. The asteroid was the thing, that came from another solar system and that's it. And there was not alien spacecraft, because it was not transmitting data, and it followed a natural trajectory. The same way the phosphine on the atmosphere of planet Venus can explain by some acid, what reaction seems like phosphine. And that thing means that we might not face the alien lifeforms in the atmosphere of the planet Venus.

Or there might be simple cells, which origin can be confirmed only if the samples of those clouds are properly analyzed. There is the possibility that those bacteria have been traveled to that planet under the core of the parachutes, or some other part, which was not sterilized.

But the fact is that we should probably determine the term "life" again. The fact is that at the absolute dry and hot places, where is not oxygen can be molecules, that can self-replicating. Those molecules can be some other than DNA. And there is the possibility that those molecules are not very complicated. So are those molecules also lifeforms or are they just self-replicating molecules? Is molecular self-replication be the description of life? Or should an organism make something else, that it is living?
